As it's been a while since last delivering any "4K" resolution OpenGL benchmarks at Phoronix, out today -- now that we're done with our massive 60+ GPU open-source testing and 35-way proprietary driver comparison -- are benchmarks of several NVIDIA GeForce and AMD Radeon graphics cards when running an assortment of Linux games and other OpenGL tests at the 4K resolution.

Debian is switching (back) to GLIBC

Debian

Five years ago Debian and most derivatives switched from the standard GNU C Library (GLIBC) to the Embedded GLIBC (EGLIBC). Debian is now about to take the reverse way switching back to GLIBC, as EGLIBC is now a dead project, the last release being the 2.19 one. At the time of writing the glibc package has been uploaded to experimental and sits in the NEW queue.

Why Migrating from Proprietary Software to Linux Is Cutting Costs for Ecommerce

A lot has changed since then. Commodity servers running Linux are the norm, virtualisation and Cloud services are common, but some organisations are still running UNIX or Windows systems because Linux migration seems like a lot of work and a big risk. It didn’t do Amazon any harm though, did it?

As you may know, Ubuntu 14.10 Utopic Unicorn will come with interesting changes. The integration of Qt 5.3 is almost done, but the developers still have to fix some known issues.

The developers hope to make Qt 5.3 available as default next week, due to the fact it has passed 99% of the tests.

My Recent Linux Journey

Linux

A journey from Windows through doubt, frustration and despair to relief and a finally joy. This journey started on 31 May 2014 the day after the release of Linux Mint 17 “Qiana” Cinnamon and finished on the 17 June 2014. I worked on this continually for 8 or more hours a day over this time can’t work at the moment so I had time on my side.

A Process for Managing and Customizing HPC Operating Systems

Filed under
GNU
Linux
Server

High-performance computing (HPC) for the past ten years has been dominated by thousands of Linux servers connected by a uniform networking infrastructure. The defining theme for an HPC cluster lies in the uniformity of the cluster. This uniformity is most important at the application level: communication between all systems in the cluster must be the same, the hardware must be the same, and the operating system must be the same. Any differences in any of these features must be presented as a choice to the user. The uniformity and consistency of running software on an HPC cluster is of utmost importance and separates HPC clusters from other Linux clusters.

It’s always nice to come across Kubuntu being used in the wild. Recently I was pointed to a refurbished laptop shop in Ireland who are selling HP laptops running Kubuntu 14.04LTS. €140 for a laptop? You’d pay as much for just the Windows licence in most other shops.

Kernel and Graphics: PDS, VKMS and Nouveau

  • PDS 0.98s release
    PDS 0.98s is released with the following changes 1. Fix compilation issue on raspberry pi. 2. Minor rework and optimization on balance code path. 3. Fix wrong nr_max_tries in migrate_pending_tasks. This is mainly a bug fix and minor optimization release for 4.17. The rework of balance code doesn't go well, it actually make more overhead than current implement. Another rework which based on current implement is still on going, hopefully be included in next release.
  • PDS-MQ CPU Scheduler Revised For The Linux 4.17 Kernel With Minor Optimizations
    Alfred Chen announced this week the release of PDS-mq 0.98s, his latest patch-set of this CPU scheduler against the Linux 4.17 upstream code-base and includes minor optimization work and bug fixes. The PDS scheduler stands for the "Priority and Deadline based Skiplist multiple queue scheduler" that is derived from Con Kolivas' former BFS scheduler with Variable Run Queue (VRQ) support. PDS design principles are to be a simple CPU process scheduler yet efficient and scalable. PDS-mq differs from Con Kolivas' current MuQSS scheduler.
  • Add infrastructure for Vblank and page flip events in vkms simulated by hrtimer
    Since the beginning of May 2018, I have been diving into the DRM subsystem. In the beginning, nothing made sense to me, and I had to fight hard to understand how things work. Fortunately, I was not alone, and I had great support from Gustavo Padovan, Daniel Vetter, Haneen Mohammed, and the entire community. Recently, I finally delivered a new feature for VKMS: the infrastructure for Vblank and page flip events. At this moment, VKMS have regular Vblank events simulated through hrtimers (see drm-misc-next), which is a feature required by VKMS to mimic real hardware [6]. The development approach was entirely driven by the tests provided by IGT, more specifically the kms_flip. I modified IGT to read a module name via command line and force the use of it, instead of using only the modules defined in the code (patch submitted to IGT, see [1]). With this modification in the IGT, my development process to add a Vblank infrastructure to VKMS had three main steps as Figure 1 describes.
  • The State Of The VKMS Driver, Preparations For vBlank & Page Flip Events
    One of the exciting additions to look forward to with the upcoming Linux 4.19 kernel cycle is the virtual "VKMS" kernel mode-setting driver. The driver is still a work-in-progress, but multiple developers are working on it.
  • NIR Continues To Be Prepped For OpenCL Support
    Longtime Nouveau contributor Karol Herbst who joined Red Hat several months ago has been working on Nouveau NIR support as stepping towards SPIR-V/compute support and this summer the work very much remains an active target.
  • Nouveau Gallium3D Moves Closer Towards OpenGL 4.5 Compliance
    While the RadeonSI and Intel i965 Mesa drivers have been at OpenGL 4.5 compliance for a while now, the Nouveau "NVC0" Gallium3D driver has been bound to OpenGL 4.3 officially. This Nouveau Gallium3D driver for NVIDIA "Fermi" graphics hardware and newer has effectively supported all of the OpenGL 4.4/4.5 extensions, but not officially. Originally the NVC0 problem for OpenGL 4.4 and newer was the requirement of passing the OpenGL Conformance Test Suite (CTS), which at first wasn't open-source. But now The Khronos Group has made it available to everyone as open-source. Additionally, the proper legal wrangling is in place so the Nouveau driver could become a conforming Khronos adopter under the X.Org Foundation without any associated costs/fees with Nouveau being purely open-source and primarily considered a community driver.

DistroWatch The Best Website For Distro Hoppers

The DistroWatch features release announcements of new versions of hundreds of Linux and other distributions. It does host reviews of distros, podcasts, and newsletters. DistroWatch first published by Ladislav Bodnar, the founder, and maintainer, on May 31, 2001. DistroWatch initially focused on Linux distributions. But later based on user requests, it went on adding different flavors of operating systems like BSD family, Android x86, Oracle Solaris, MINIX, and Haiku etc. The DistroWatch presents detailed information at one place in a very convenient manner. At the time of writing this article, the DistroWatch hosted information of more than 300 active distributions (referring the list of distros populated under drop-down feature on the first page of the DistroWatch) and more than hundred in queue. It is said that the DistroWatch lives out of advertising and donation. LinuxCD.org is the first to advertise on the DistroWatch site. Read more

Ubuntu 18.04 LTS and 16.04 LTS Amazon Linux AMIs Now Support Amazon's SSM Agent

As of July 2018, Amazon's Linux AMIs (Amazon Machine Images) that are based on either the Ubuntu 16.04 LTS (Xenial Xerus) or Ubuntu 18.04 LTS (Bionic Beaver) operating systems now come pre-installed with the AWS Systems Manager Agent (SSM Agent), an Amazon software designed to run on hybrid or Amazon EC2 instances in public and private clouds on AWS (Amazon Web Services). "With this new feature release, AWS Systems Manager Agent is installed by default on all instances launched or built from Ubuntu 16.04 LTS (2018.07 and later) and 18.04 LTS (all versions) AMIs," said Amazon. "By having the agent pre-installed, you can quickly start using AWS Systems Manager features such as Run Command, State Manager, Inventory and Patch Manager." Read more
